Description

Technical Field

[0001] This utility model relates to the field of gas burner technology, specifically to a guide plate for gas mixing. Background Technology

[0002] Gas burners, as key equipment for mixing gas and air and then burning them, are widely used in industrial and civil fields, such as gas stoves, boilers, heating furnaces, and wall-hung boilers. Currently, the structure of gas burners on the market mainly includes the burner body, fuel nozzle, air passage, mixing device, ignition device, and combustion chamber.

[0003] Existing burners exhibit several problems during operation that urgently need to be addressed. These include deflagration and knocking issues, specifically uneven gas mixing and distribution within the mixing chamber at the burner cap. This leads to situations where some areas ignite easily and burn more completely, while others are more difficult to ignite and burn incompletely. This can easily affect combustion stability, potentially causing deflagration during ignition and knocking due to gas backflow during flameout. Consequently, it is detrimental to maintaining combustion stability and thermal efficiency. The primary cause lies in the instability of the airflow. The gas-air mixture is not properly guided during mixing, resulting in an uneven and unstable mixture. Upon reaching the combustion plate, this mixture cannot form stable combustion, leading to localized high and low gas concentrations, and sometimes gas backflow, resulting in knocking.

[0004] It is evident that existing burners still have room for improvement and should be optimized to improve their structure. This optimization should focus on the mixing chamber to enhance the uniformity of gas-air mixing, ensuring good flow characteristics and concentration uniformity of the mixture upon entering the combustion chamber. This results in a more stable airflow and more uniform gas-air mixing, thereby guaranteeing the burner's stability and reliability. Therefore, a more reasonable technical solution is needed to address the technical problems existing in the current technology. Utility Model Content

[0005] To overcome at least one of the aforementioned defects, this utility model proposes a guide plate for gas mixing, which aims to guide the mixed flow of gas and air, help the gas and air maintain a stable flow during the flow process, mix evenly, help form stable combustion, and avoid deflagration and knocking phenomena.

[0006] To achieve the above objectives, the guide plate disclosed in this utility model can adopt the following technical solution:

[0007] A guide plate for mixing gas is used to cover the upper part of a gas injection pipe and cooperate with the lower part of a flow divider. The guide plate includes an integrally formed central ring and an outer ring. The outer ring and the central ring are concentrically arranged. The central ring forms a central through hole that cooperates with the flow divider. Several flow guides are provided at the edge of the central through hole. When the gas mixture of fuel gas and air is delivered from the gas injection pipe to the lower part of the guide plate, it rises from the flow guides to the upper part of the guide plate.

[0008] The aforementioned guide plate, in conjunction with the gas ejector pipe and the flow divider, guides the mixed gas from the gas ejector pipe to the upper flow divider in an orderly manner. The flow divider is located inside the mixing chamber, thereby forming a stable airflow, which facilitates subsequent stable combustion. This not only improves the quality of combustion but also helps to eliminate deflagration and knocking noise.

[0009] Furthermore, the central through-hole is used to cooperate with the gas ejector pipe and the flow divider plate. Its structure is not uniquely limited. Here, we optimize and propose one feasible option: the central through-hole includes a circular hole, and the flow guide includes an arc-shaped opening extending outward from the edge of the circular hole. When adopting the above scheme, the number of flow guides in the central through-hole is not limited. When multiple flow guides are provided, the flow guides are evenly spaced along the edge of the circular hole.

[0010] Furthermore, after the central through-hole is set, structural optimization can be performed to help the guide plate better cooperate with the gas ejector pipe. The structure is not limited to a single design; one feasible option is proposed here: the central through-hole and the guide port are connected to form an integral through-hole. A hole edge perpendicular to the hole opening is formed inside the through-hole, and the shape of the hole edge is consistent with the shape of the hole opening. With the above solution, the hole edge and the central ring are integrally formed, and the thickness of the hole edge is equal to the thickness of the central ring.

[0011] Furthermore, an auxiliary guide plate is fixedly fitted along the edge of the central through hole, the edge of which is used to correspond to and fit against the inner edge of the gas ejector pipe. When using the above scheme, the edge of the central through hole can be at the same height as the inner edge of the gas ejector pipe.

[0012] Furthermore, this invention improves the installation stability of the guide plate by optimizing its structure: a recessed groove is formed on the outer side of the through hole, and the direction of the recessed groove is consistent with the shape of the hole opening. When the above solution is adopted, the wall of the recessed groove is vertical, forming a groove with uniform width.

[0013] Furthermore, the bottom surface of the sinking trough, used to fit the gas ejector pipe, can be constructed in various forms. Here, we optimize and propose one feasible option: the bottom surface of the sinking trough is a plane, used to fit and maintain a fit with the upper end face of the gas ejector pipe. When using the above scheme, the width of the bottom surface of the sinking trough can be equal to its depth.

[0014] Furthermore, the structure of the central ring can adopt various schemes, and its structure is not limited to one. Here, we optimize and propose one feasible option: the central ring includes a horizontal ring surface, the plane where the central through hole is located is lower than the central ring, and the upper port of the hole edge is located on the horizontal ring surface where the central ring is located.

[0015] Furthermore, the structure of the outer ring can adopt various schemes. Here, we optimize and propose one feasible option: the outer ring includes an inclined annular surface, the inner side of the outer ring is connected to the outer edge of the central ring, and the inner side of the outer ring forms a gradually descending inclined annular surface outward. When adopting the above scheme, the downward inclination angle of the outer ring is less than 30°.

[0016] Furthermore, a horizontal outer edge buckle is formed on the outermost side of the outer ring portion.

[0017] Furthermore, the central ring portion and the outer ring portion are integrally formed.

[0018] Compared with the prior art, some of the beneficial effects of the technical solution disclosed in this utility model include:

[0019] This invention optimizes the structure of the guide plate to guide the mixed gas from the gas ejector pipe into the upper mixing chamber, helping to achieve uniform and stable gas flow, which promotes subsequent stable combustion, thereby improving combustion efficiency, avoiding deflagration, and eliminating detonation.

When using the above scheme, the central through hole 3's edge 5 can be at the same height as the inner edge of the gas ejector pipe 8.

[0038] This embodiment also improves the installation stability of the guide plate by optimizing its structure: a recessed groove 6 is formed on the outer side of the through hole, and the direction of the recessed groove 6 is consistent with the shape of the hole opening. When the above scheme is adopted, the groove wall of the recessed groove 6 is a vertical surface, forming a groove with a uniform width.

This embodiment optimizes and adopts one feasible option: the bottom surface of the sinking trough 6 is a plane, and the bottom surface of the sinking trough 6 is used to fit and maintain a fit with the upper end face of the gas ejector pipe 8. When the above scheme is adopted, the width of the bottom surface of the sinking trough 6 can be equal to its depth.
